A few weeks ago I posted about Death To The Stock Photo, a free service that sends you a pack of hi-res lifestyle photos each month directly to your inbox.
Now here's Unsplash. A simple sign up and you receive 10 free hi-res photos, every 10 days.
If you don't want to sign up, the homepage allows for direct downloads from a gallery of really nice images, such as the one above. Another great feature of Unsplash is that you can also submit your own photos to be distributed freely if you wish.
Let me know if you sign up!
